Product details
Overview
ADP3193JCPZ-RL from Analog Devices is an 8-bit programmable, 2- to 3-phase synchronous buck controller optimized for Intel® VR10.x/VR11 core voltage regulation. It delivers ±7.7 mV worst-case differential sensing error over temperature, supports 0.5 V–1.6 V output via internal VID DAC, and operates up to 1 MHz per phase with logic-level PWM outputs for external high-power drivers.
For engineers reviewing the ADP3193JCPZ-RL datasheet, ADP3193JCPZ-RL pinout, ADP3193JCPZ-RL application, or ADP3193JCPZ-RL equivalent, key selection criteria include programmable phase count (2/3), active current balancing across phases, digitally adjustable short-circuit latch-off delay, enhanced PWM flex mode for load transient response, and built-in power-good/crowbar blanking for on-the-fly VID changes.
Technical Context
The ADP3193JCPZ-RL implements a multimode PWM architecture with independent phase control logic, enabling selectable 2-phase (PWM3 tied to VCC) or 3-phase operation. Its internal 8-bit VID DAC reads processor voltage identification codes directly to set output between 0.5 V and 1.6 V, referenced to FBRTN with 65–200 μA bias current.
Current sensing uses a dedicated CSA with CSSUM/CSREF/CSCOMP terminals for DCR- or resistor-based total output current measurement; offset voltage is ±1.0 mV. Phase current balancing is achieved via SW1–SW3 inputs monitoring switch-node voltages, with programmable thermal balance through external series resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Range | 0.5 V to 1.6 V, digitally set by 8-bit VID code per VR10.x/VR11 spec - enables dynamic CPU voltage scaling. |
| Differential Sensing Error | ±7.7 mV max over 0°C–85°C - ensures tight remote-sense regulation accuracy at microprocessor VDD sense point. |
| Phase Configuration | Selectable 2- or 3-phase operation - configured by PWM3 pin state; supports scalable current delivery up to ~100 A with interleaving. |
| Switching Frequency | Up to 1 MHz per phase (master clock up to 4 MHz, divided by phase count) - balances efficiency vs. VR size in desktop PC power supplies. |
| Current Balance Accuracy | Active per-phase current balancing using SW1–SW3 inputs - maintains thermal equilibrium and extends MOSFET lifetime under asymmetric loads. |
| Short-Circuit Protection | Programmable latch-off delay via CDELAY capacitor - configurable fault hold time prevents nuisance tripping during transient overload. |
| Power-Good Delay | 2 ms blanking during soft start and 100–250 μs during VID changes - accommodates on-the-fly voltage transitions without false PWRGD assertion. |
Pinout & Package
The ADP3193JCPZ-RL is housed in a 32-lead LFCSP (Lead Frame Chip Scale Package) with exposed EPAD electrically connected to GND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Enable input | Pulling low disables all PWM outputs and forces PWRGD low - provides system-level power sequencing control. |
| PWM1–PWM3 (Pins 22–20) | Logic-level PWM outputs | Drive external gate drivers (e.g., ADP3120A); PWM3 tied to VCC selects 2-phase mode - enables flexible topology configuration. |
| SW1–SW3 (Pins 19–17) | Phase current sense inputs | Monitor switch-node voltages for per-phase current balancing - allows thermal optimization via external series resistors. |
| VID0–VID7 + VIDSEL (Pins 31–24, 32) | Voltage ID interface | 8-bit parallel bus with VIDSEL selecting VR10/VR11 decoding - directly interfaces Intel CPU VID signaling without glue logic. |
| FB / FBRTN (Pins 4 / 3) | Differential feedback pair | Remote sensing at CPU VDD/VSS points; FBRTN carries only 65–200 μA - minimizes IR drop impact on regulation accuracy. |
| CSREF / CSSUM / CSCOMP (Pins 11–13) | Current sense amplifier terminals | Support DCR or resistor-based total output current measurement; ±1.0 mV offset enables precise droop and OCP. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced PWM flex mode | Enables immediate phase response to load step-up events - reduces output voltage undershoot by eliminating wait-for-next-cycle latency. |
| Digitally programmable output range | 0.5 V–1.6 V via 8-bit VID with VR10.x/VR11 compatibility - eliminates need for external DAC or voltage-setting resistors. |
| Active current balancing | Real-time per-phase current matching using SWx inputs - maintains equal thermal stress across MOSFETs and inductors. |
| Programmable short-circuit latch-off delay | Configurable via CDELAY capacitor (e.g., 8 ms typical with 10 nF) - prevents false shutdown during inrush or brief overload. |
| Built-in power-good/crowbar blanking | Hardware-masking of PWRGD and crowbar during VID transitions - ensures stable CPU voltage handoff during frequency/voltage scaling. |

FAQ
What is the operating temperature range specified for the ADP3193JCPZ-RL?
The ADP3193JCPZ-RL is specified over the extended commercial temperature range of 0°C to 85°C ambient. Its junction temperature is rated to 125°C, and thermal impedance (θJA) is 32.6°C/W. This range supports reliable operation in densely packed desktop motherboard VRM sections where airflow is limited and localized heating occurs near CPU power delivery circuits. The ADP3193JCPZ-RL maintains ±7.7 mV differential sensing error across this full range.
How does the ADP3193JCPZ-RL configure 2-phase versus 3-phase operation?
The ADP3193JCPZ-RL automatically detects phase count during startup: tying PWM3 (Pin 20) to VCC places it in high-impedance state and configures 2-phase operation, while leaving PWM3 floating enables full 3-phase mode. Internal phase detection occurs during the first three clock cycles of TD2 in the start-up sequence. This method avoids external configuration pins and preserves pin count for critical functions like CSREF and CSSUM. The ADP3193JCPZ-RL supports up to 1 MHz per phase in either configuration.
What external components define the ADP3193JCPZ-RL's switching frequency?
The ADP3193JCPZ-RL's master oscillator frequency is set by an external resistor (RT) connected from Pin 9 (RT) to GND. Frequency ranges from 250 kHz to 4 MHz depending on RT value (e.g., 210 kΩ yields ~260 kHz in 3-phase mode). The per-phase frequency equals master clock divided by active phase count (÷2 for 2-phase, ÷3 for 3-phase). This resistor-based tuning allows precise optimization of efficiency, ripple, and component size without firmware or digital registers.
Can the ADP3193JCPZ-RL support both VR10.x and VR11 voltage identification protocols?
Yes - the ADP3193JCPZ-RL supports both VR10.x and VR11 specifications via the VIDSEL pin (Pin 32). When VIDSEL is low, the internal DAC decodes VID0–VID7 as VR10.x (7-bit + 1-bit); when high, it interprets all eight bits as VR11. This dual-mode capability allows single-bom flexibility across Intel processor generations. The ADP3193JCPZ-RL's 0.5 V–1.6 V output range and ±7.7 mV accuracy meet both standards' regulation requirements.
What is the purpose of the CSREF, CSSUM, and CSCOMP pins on the ADP3193JCPZ-RL?
These pins form the dedicated current sense amplifier (CSA) interface: CSREF (Pin 11) serves as the reference voltage node connected to the output rail; CSSUM (Pin 12) is the summing node for inductor DCR or sense-resistor currents; CSCOMP (Pin 13) sets gain and compensation via external RC network. Together, they enable accurate total output current measurement (±1.0 mV offset) for voltage positioning and overcurrent protection - critical for maintaining load-line compliance and preventing thermal runaway in multiphase VRMs. The ADP3193JCPZ-RL uses this path for both droop control and short-circuit detection.
